The package can load and cache static, prerendered map tiles from a
variety of sources including OpenStreetMaps, Bing Maps, and so on.

It includes a geocoder query service which maps free-text queries to
regions of the planet's surface. The service can be backed by the
Nominatim service (associated with OpenStreetMaps), the Bing geocoder,
the Google geocoder, and so on.

Selection of tilesets is independent of selection of geocoder, so you
can mix and match.

The package includes a "slippy map" morph called TiledMapMorph, that
allows interaction with a map using the mouse. It includes a few hooks
for EToys, too, so EToys scripting of the map is possible.

I've recorded a short (< 10 min) demo video showing the package in action:

PS. All the Bing services require an API key. You can get one of your
own from https://www.bingmapsportal.com/. Included in the package are a
few other tile sources and geocoders that need API keys as well - you'll
need to check the websites and terms&conditions for each service you
want to use.
